摘要
在大型工程的岩土工程勘察中,如何确定岩石地基的承载力,直接影响到建筑的质量、造价和进度。载荷试验作为模拟建筑物基础受力条件的试验,科学、直观地提供了地基的承载力和变形模量,给设计部门提供了不可或缺的设计依据。然而,岩基载荷试验结果受基岩埋深及孔径的影响尚不清楚。利用ABAQUS有限元分析软件,对深层岩基载荷试验影响因素进行数值模拟分析,得出的结论可为今后岩土工程勘察提供借鉴。
In geotechnical engineering investigation of large-scaled projects, the determination of bearing capacity for rock foundations directly affected the construction quality, cost and schedule. Load test as a test simulate loading conditions of building foundations proved that the foundation bearing capacity and deformation modulus scientifically and intuitively, which was the indispensably design basis for design department. However, buried depth of bedrock and bore hole affected the results of the batholith load test was not clear yet. The software of ABAQUS finite element analysis was used to numerical simulation analysis of the influence factors about batholith load test. The conclusions can be provided reference for future geotechnical engineering investigation.
